Hi Guys and Girls. Thanks for all the input this forum has. I have been able to follow everything and do all the mods on my 2003 patrol gu 3.0L
I purchased a needle and dawes valve and have followed instructions from this forum on how to fit it. My needle valve works as I have played with the spool up rate.
I have wound the dawes out to bring boost down and it does not appear to be doing that. I have boost going to 20psi at 3000rpm. No matter what I do this does not change.
I have replaced the hoses, pulled the dawes apart to check that nothing had fallen into it but it does not matter.
Any help would be greatly appreciated.
